We recently had the electrical planning meeting. During this process, the following plan was created. Unfortunately, no furniture is shown, so I have also included a floor plan with furniture. This is our first time doing something like this. I would appreciate your feedback, as I am sure you can provide valuable advice and some helpful suggestions.

I am particularly uncertain about the kitchen, main bathroom, and staircase areas.

About the house:
- 3 floors: basement + ground floor + upper floor
- approximately 258 sqm (2773 sq ft) of living space on each of the 3 floors
- ceiling height on ground and upper floors: about 2.55 m (8.4 ft)
- ceiling height in basement: about 2.38 m (7.8 ft)

Questions:
Should I really install 5 ceiling light outlets in the kitchen? Although a lot of light is needed, I wonder if this might be too many.
What do you think about the wall outlets in the staircase area?
For rooms of at least 16 sqm (172 sq ft), I have always planned two ceiling outlets. Do you think it is also necessary if the room is, for example, 16.5 sqm (178 sq ft)?
Should I run a cable for illuminated washbasins?
Is a 50 mm (2 inches) empty conduit sufficient for photovoltaics?

Here is the kitchen layout plan being used. Electrical outlets and water connections are marked, but the lighting plan is not included.

Regarding the wall lamps: In our home, all of them are mounted at about 195 cm (77 inches) height and shine exclusively upwards. This creates nice indirect lighting (each dimmable) in both the living room and the dining room. There are three lamps in the living room and two in the dining room. Additionally, we have a lamp above the dining table in the dining room and adjustable surface-mounted spotlights (not recessed) in the living room.

A 50mm (2 inch) conduit is sufficient—it should be dedicated solely for that purpose. Currently, I have only two strings and am considering adding a third. Having a spare is always good.

Kitchen: Definitely install ceiling outlets above the countertops and any potential table. Plenty of sockets are essential, including at possible seating areas, whether for a toaster or phone charging.

In the living room, I installed everything needed for the TV at two potential locations—which has already come in handy. In the basement, I initially installed only one ceiling outlet per room, which turned out to be a bad idea. It was quite a hassle to neatly mount three lamps afterward.

In my music room, I ran dedicated, directly laid cables (which halves the cable length) with a larger cross-section from the distribution panel to the amplifiers. In the garage, I installed a heavy-duty cable for a possible electric car.

For future needs, I routed cables under the roof for possible spotlights, in the basement inside all drain pipe casings, and in every bathroom to accommodate potential high-tech toilets. Wherever I might hang artwork, I installed a corresponding wall outlet opposite the spot.

My house is equipped with a total of 16 satellite outlets, 25 speaker runs, and 120 network ports. This is probably overkill, but I have used a surprisingly large number of them. Most importantly, you never know in advance which ones you will never use after 40 years.

In the next house, I would separate lighting and power outlets. All emergency lighting should be on a separate circuit.

I have only one 50mm (2 inch) conduit. I wanted to install another one, but the basement ceiling is already finished—I missed that opportunity. 🙁

Thanks for the tip about the basement; I have now spontaneously planned an additional ceiling outlet in basement room 1 since it is quite large at 32m² (344ft²).

Lighting was actually one of the aspects we were unhappy with in our early house. It makes a huge difference in terms of well-being.

Can anyone respond to my questions?

Should I really install 5 ceiling light fixtures in the kitchen? While a lot of light is needed, I wonder if that might be excessive.

What do you think about the wall fixtures in the stairwell? Is the lighting from the 2 wall fixtures sufficient?

For rooms that are at least 16 square meters (172 square feet), I have always planned for 2 ceiling fixtures. Do you think it’s necessary if the room is, for example, 16.5 square meters (177 square feet)?

Should I run a cable for illuminated vanity mirrors?
